LUBRICATING DEVICE FOR SPINNING-MACHINES.,

SPECIFICATION forming part of Letters Patent No. 597,331, dated January 11, 1898.

' Application tiled May 3, 1897. Serial No. 634,815. (No model.)

To @Zt wto'm t may concern:

Be it known that I, LENDER SHEPARD, of Brunswick, in the county of Cumberland and State of Maine, have invented an Improvenient inLubricating Devices for Spinning Machines, of which the following description, in connection with the accompanying drawings, is a speciiicationdike letters on the drawings representing like parts.

This invention has for its object to provide novel means for lubricating spindles and bolsters of spinning-machines, my invention relating more especially to means which I have devised for lubricating a plurality of spin dies and holsters through one and the same oil-supplying pipe.

In that class of spinning machinery Where the spindle turns in a bolster supported on a bolster-rail, the bolster-bearing being located above the bolster-rail, it is customary to oil each bearing separately by means of an oilcan.

Figure l, in front elevation, shows a sumcientportion of a spinning-machine of one variety with my improvement added to enable my invention to be understood, one ot the bolsters and its support being shown in elevation, while the other is represented in section. Fig. 2 is a top or plan view of one of the holstersJ its support, and part or" the bolster-rail. Fig. 3 is a section through the bolster and its support and lubricating apparatus in the line a; of Fig. 2a Fig. e shows a diiierent form of bolster-support With my iinprovement added.

Referring to Figs. 1 to 3, showing part of a rovingframe,A represents a revoluble spindle; A', a bolster-rail; B, a support connected therewith by a suitable bolt O, and B' a bolster, sustained by said support, the said bolster, as best represented at the right in Fig. l, being chambered to leave a bearing b in Contact with the spindle. `These parts are and may be of any usual or suitable kind, and in practice they may be operated in usual manner.

The bolster-support contains in its chambered portion a thin tube c, the lower end of which is expanded oil-tight in the bolsterany suitable manner a piece of textile or other fabric, as f, which by contact with the oil in the oil-space g left between the said tube and the interior of the bolster will act by capillary attraction to draw the oil to the top of the tube c, Where it will be applied to the rotating spindle and Will lubricate it and its bearings in the bolster as the spindle and bolster change their relative vertical positions in operation in usual manner. The bolster-support, as shown best in Fig. 3, is bored to present an opening leading into the oil-chamber g referred to, and said opening receives an induction-pipe it, the upper end of which is herein represented as provided with a head h', extended horizontally therefrom in opposite directions, the face of the head being concaved to receive Within it a suitable pipe, as fm, which may be of lead or tin or any other suitable material, the said pipe being kept seated in the concave seat ot' the head h by means of a cap h2, laid on the outer side of the pipe, suitable rings or collars, as h3, slipped on the head of the cap, acting to hold the same iirmly in contact with the pipe and keep the pipe firmly seated.

After the bolster-supports have been secured in proper position upon the bolstenrail the pipe m is laid in the seat of the head h', and with a suitable drill the operator drills a hole through the pipe, as at u, said hole in tersecting the induction-orice n', so that when the oil is put into a suitable vessel or receptacle in communication with the pipe m the oil will loW through said pipe and will enter all of the induction-pipes and enter the oil-space g.

At the left in Fig. l I have shown the bolster B as provided with a sleeve G, having a disk G', on which rests the lower end of the spool or bobbin, and said sleeve has connected With it a toothed gear G2, of usual construction, the said sleeve and disk being revolved to rotate the spool or bobbin at the proper speed, and to lubricate this sleeve Where it rotates on the stationary bolster B, I have provided the bolster with an induction-ori?.

nce p, (represented by a dotted line in Fig. l and by full lines in Fig. 3,) which orifice, in

communication with the oil-space g, may be through the felt or leather in the said orifice i p, as required. The librou's material f may extend downwardly more or less into the oilspace g. p

It is customary when oiling the parts of the particular machines shown in Figs. l to 3 to Y apply oil directly to the spindle above the top of the bolster, the oil so applied on the spi-n'-V i dle lubricating the interior of the bolster, and j some of the oil so applied runs down the outside ot' the bolster and oils the bobbin-.carrying sleeve, which runs 'on the bolster. In this old plan any excess of voil (and there is most always an excess unless the greatest Ycare is used) gets upon the base of the sleeve 'and in the rotation of the sleeve is thrown 'oii centrifugally, and, -meeting the roving, soils the same, or is thrown off and falls on the floor or onother parts of the machine; but in this my invention only a proper amount of oil,

never an excess, is applied to the spindle and Fig. 4 shows a supporting-case H, of usual construction, it being seated on a rail H by a nut H2, and this supporting-case has an inductiontube H3 provided, as described of the inductiontube 7L, Fig. 3, with an extension forming a head h', which is concave to receive the oil-conveying pipe m, a cap h2 lying on'the outside of the pipe and being held in the seat of the head h by means of suitable rings or clamps, as h3, before described. By means of a pipe connected with this class of spindle-supports a gang of them can be oiled simultaneously instead of oiling them separately.

This invention is not limited tothe particular means shown for connectin g the oil-supply pipe m with the tube having the induction-orifice, nor to the particular shape of the said tube, so long as it conveys oil to the oilchamber in the bolster.

Having described my invention, what I claim as new, 'and desire to secure by Letters Patent, is v l. A series of holsters and their supports having induction orifices extended therefrom, and an oil conducting or feeding pipe seated in theouter end o'f said induction-oriices, 'said pipe being perforated for the pas'- sage of oil in the said induction-orices, combined with clamping means to seat said pipe oiletight upon or with relation to said induction-tubes, substantially as described.

2. A bolster having a bearing b at its upper end for a spindle, combined with a tube located Within said bolster and connected oil- Ytight with the lower end thereof, said tube being extended upwardly within said bolster and terminatingbelow the lower end of said bearing, leaving an oilspace between the external wall of said tube and the internal wall of said bolster, said bolster being provided with an induction-orifice to lead oil through it and into the space between itself and the said tube tooperate, substantially as described.

3. A bolster provided with a tube located within it and connected oil-.tight with the lower end of saidv bolster, said tube being extended upwardly within said bolster, leaving an oil-space between its external wall and the internal wall of the bolster, and fibrous ma terial located in said 'oil-'space to conduct the oil by capillary attraction to the top of said tube, substantially as described.

4. A plurality of bolster-supports and connected holsters, a tube contained within each of said bolsters and .joined oil-tight at its lower end with the bolster, the tube being or' smaller diameter externally than the interior of the bolster to leave an oil-space, each or' said bolster supports having an inductiontube combined with an' oil-conducting pipe seated in or connected with said oil-induction tubes, to simultaneouslyjoil a series of said bolstersupports and bolsters and spindles running therein, substantially as described.

5. A bolster provided with a tube located within it to leave an oil-chamber between the said tube and the said bolster, and having an oil-delivery opening provided with an oil-conducting plug combined with a sleeve applied to the'exterior of and rotatable on said bolster, the said plug delivering oil from the said oil-chamber between the said sleeve and bolster to lubricate the same, substantially as described.

6. A bolster provided at its interior with a tube of less diameter than the interior of the bolster-to leave between said tube and bolster an oil-chamber, said bolster also having an oil-delivery opening in communication with said oil-chamber, and a piece of fibrous material as f located at the upper end of said tube and extended into said oil-chamber, 'combined with a spindle extended through said tube and bolster, and a revoluble sleeve surrounding said bolster outside said oil-delivery opening whereby oil in said oil-chamber is delivered not only to said spindle but also to said sleeve to lubricate both of them, substantially as described.

"7. A series of bolsters and their supports havin g induction-orifices extended therefrom,

the outer ends of said induction-orifices being provided with `concaved extensions, an oil conducting or feeding pipe seated in the outer IIO ends of a plurality of said induction-orifices, name to this specification in the presence of a seiesof semioircuiar caps applied to said two subscribing Witnesses.
